Description

Die Erfindung bezieht sich auf eine lichtdurchlässige, zum Beispiel transparente Deckfolie, die zum Ankleben an eine optional Information tragende Oberfläche gedacht ist.The The invention relates to a translucent, for example transparent Cover foil, which adheres to an optional information-carrying surface thought is.

Solch eine Deckfolie ist bekannt. Diese bekannte Folie weist eine erst Schicht aus Polyester und eine druckempfindliche oder wärmeaktivierte Klebeschicht auf, die damit verbunden ist.Such a cover sheet is known. This known film has a first Layer of polyester and a pressure-sensitive or heat-activated adhesive layer which is connected with it.

Es ist eine Aufgabe der Erfindung, eine Deckfolie derart auszuführen, daß sie eine Kombination zweier Aspekte anbieten kann, d. h., eine erste Schicht, die mit einem Aufbau versehen ist, und eine wärmeaktivierte Klebeschicht. Der bestehende Aufbau darf nicht nachteilhafterweise beeinflußt werden, wenn die Klebeschicht aktiviert wird.It An object of the invention to carry out a cover sheet so that they have a Combination of two aspects, d. h., a first layer, which is provided with a construction, and a heat-activated adhesive layer. The existing structure must not be adversely affected if the adhesive layer is activated.

Die beschriebene bekannte Folie erfüllt nicht diese Anforderungen.The complies with known film described not these requirements.

Es ist daher eine Aufgabe der Erfindung, eine lichtdurchlässige Deckfolie vorzusehen, die einen Aufbau aufweist, zum Beispiel eine Struktur und/oder ein Muster, das aus ihrer Hauptoberfläche gepreßt ist, während Vorsehungen ebenfalls vorhanden sind zum Ankleben der Folie an eine Oberfläche zum Abdecken unter Benutzung einfacher Mittel ohne nachteilhafterweise den bestehenden Aufbau zu beeinflussen.It is therefore an object of the invention, a translucent cover sheet to provide, which has a structure, for example, a structure and / or a pattern that is pressed out of its main surface while providence as well are present for adhering the film to a surface for Covering using simple means without disadvantageously to influence the existing structure.

In Hinblick auf das Obige sieht die Erfindung eine lichtdurchlässige Deckfolie vor, die gedacht ist, klebend an einer Oberfläche, zum Beispiel der Oberfläche einer Trägerplatte angebracht zu werden, die optional Information, wie Buchstaben, Zahlen, Bilder oder ähnliches trägt, wobei die Folie aus einem Laminat besteht, mit:

  • einer ersten Schicht, die nur bei einer relativ hohen ersten Temperatur, zum Beispiel in dem Bereich von 120°C–200°C plastisch verformbar ist und die zum Beispiel Polykarbonat, PMMA, PVC, ABS, PP, PF aufweist, welche erste Schicht vor, während oder nach Verbinden mit den anderen Schichten versehen wird mit einem Aufbau, zum Beispiel einer Struktur und/oder einem aus ihrer Hauptoberfläche herausgepreßten Muster durch Ausüben von Druck und erhöhter Temperatur auf mindestens die erste Temperatur durch zum Beispiel Anlegen einer erwärmten Profilrolle;
  • einer zweiten Schicht, die daran anklebt, die aus einer abmessungsmäßig stabilen Trägerschicht mit zum Beispiel Polykarbonat, PMMA, PVC, Polyester/PET, ABS besteht; und
  • einer dritten Schicht, die daran anklebt, die schmelzbar und somit wärmeaktiviert bei einer relativ niedrigen zweiten Temperatur, zum Beispiel in dem Bereich von 50°C–90°C ist und die aus einer hoch-schmelzenden Schicht oder Klebeschicht mit zum Beispiel EVA, EEA, EBA, EMA, GBA. oder andere niedrig-schmelzende Kunststoffe einschließlich Polyolefine und Copolymerester, Polyacetatester, Weich-PVC besteht;
  • welche Schichten gegenseitig durch Klebstoffe, z. B. unter Benutzung von Koextrusion miteinander verbunden sind.
In view of the above, the invention provides a translucent cover sheet which is intended to be adhesively attached to a surface, for example the surface of a support plate, which optionally carries information such as letters, numbers, images or the like, the film comprising a laminate, with:
  • a first layer which is plastically deformable only at a relatively high first temperature, for example in the range of 120 ° C-200 ° C and which comprises, for example, polycarbonate, PMMA, PVC, ABS, PP, PF, which first layer during or after bonding to the other layers is provided with a structure, for example a structure and / or a pattern extruded from its main surface, by applying pressure and elevated temperature to at least the first temperature by, for example, applying a heated profile roll;
  • a second layer adhered thereto consisting of a dimensionally stable support layer comprising, for example, polycarbonate, PMMA, PVC, polyester / PET, ABS; and
  • a third layer adhered thereto which is fusible and thus heat activated at a relatively low second temperature, for example in the range of 50 ° C-90 ° C, and that of a high melting layer or adhesive layer with, for example, EVA, EEA , EBA, EMA, GBA. or other low-melting plastics including polyolefins and copolymer esters, polyacetate esters, plasticized PVC;
  • which layers each other by adhesives, for. B. are interconnected using coextrusion.

Die Aufmerksamkeit wird auf die Tatsache gelenkt, daß Polyester/PET als Material für die erste Schicht ausgeschlossen ist.The Attention is drawn to the fact that polyester / PET as a material for the first layer is excluded.

Die Erfindung beruht auf der Einsicht, daß das Aufbauen der ersten Schicht zuvor stattfinden kann und daß aufgrund der relativ hohen Erweichungstemperatur des angelegten Materiales, in der Größenordnung von zum Beispiel 180°C, wenn die Klebeschicht aktiviert wird, zum Beispiel bei einer Temperatur von 70°C, die erste Schicht einschließlich ihres Aufbaues nicht beeinflußt wird, während die Klebeschicht trotzdem voll aktiviert wird, so daß die Deckfolie wirksam an der Oberfläche zum Abdecken angeklebt werden kann.The The invention is based on the insight that the construction of the first layer can take place before and that due the relatively high softening temperature of the applied material, in the order of magnitude of for example 180 ° C, when the adhesive layer is activated, for example at a temperature of 70 ° C, including the first layer their structure is not affected will, while the adhesive layer is still fully activated, so that the cover sheet effective on the surface can be glued to cover.

Die zweite Schicht, die zum Beispiel aus Polyester besteht, ist zu einem großen Maß nicht dehnend und nicht schrumpfend. Diese Schicht macht es auch möglich, einen Streifen der Deckfolie in einer Laminierungsmaschine zu erwärmen, ohne daß dieses in einer Erweichung der gesamten Deckfolie derart resultiert, daß die Leichtigkeit der Handhabung derselben begrenzt ist.The second layer, which consists for example of polyester, is one huge Not measure stretching and not shrinking. This layer also makes it possible to have one Strip the cover sheet in a laminating machine without heating that this resulting in a softening of the entire cover sheet such that the ease the handling of the same is limited.

Eine spezielle Ausführungsform weist das spezielle Merkmal auf, daß die erste Schicht und die zweite Schicht aus einer integralen, chemisch im wesentlichen homogenen Schicht bestehen. Die Aufmerksamkeit wird wieder auf die Tatsache gelenkt, daß Polyester als Material für die erste Schicht ausgeschlossen ist. In diesem Falle müssen daher beide integrierten Schichten aus einem Material bestehen, von dem Polyester/PET ausgeschlossen ist.A special embodiment has the special feature that the first layer and the second Layer of an integral, chemically substantially homogeneous Layer exist. The attention is again on the fact steered that polyester as material for the first layer is excluded. In this case, therefore, must both integrated layers consist of a material of which Polyester / PET is excluded.

Eine spezielle Ausführungsform weist das spezielle Merkmal auf, daß die Klebstoffe eine klebverstärkende Aktivierung der mindestens einen Klebeoberfläche, zum Beispiel eine Koronabehandlung, insbesondere in dem Fall von Polyester und Polypropylen, aufweisen. Andere zugehörige Behandlungen, wie Ionenbombardierung, können ebenfalls geeignet sein.A special embodiment has the special feature that the adhesives have an adhesive-enhancing activation the at least one adhesive surface, for example, a corona treatment, especially in the case of Polyester and polypropylene. Other related treatments, such as Ion bombardment, can also be suitable.

Das Kleben zwischen den verschiedenen Schichten kann im Prinzip auf jede geeignete Weise stattfinden. Eine spezielle Ausführungsform ist die, bei der die Klebstoffe eine Klebeschicht, wie eine Schicht einer Grundierung, aufweisen, die an beiden Oberflächen zum Kleben anhaftet.The Sticking between the different layers can in principle be up take place in any suitable way. A special embodiment is the one where the adhesives are an adhesive layer, like a layer a primer, which on both surfaces for Sticking sticks.

Alle geeigneten Mittel können zum Versehen der ersten Schicht mit einem Aufbau betrachtet werden. Eine spezielle Ausführungsform ist die, bei der die erste Schicht zuvor mit einem Aufbau durch eine mechanische, chemische und/oder physikalische Behandlung oder durch eine Deckschicht versehen ist, die einen Aufbau bildet, zum Beispiel durch Dampfabscheiden, Sputtern oder ähnliches.All suitable means can to be considered for providing the first layer with a construction. A special embodiment is the one where the first layer was previously constructed with a build a mechanical, chemical and / or physical treatment or is provided by a cover layer forming a structure, for Example by vapor deposition, sputtering or the like.

Im allgemeinen wird die Erweichungstemperatur der ersten und dritten Schicht deutlich unterschiedlich sein, zum Beispiel in der Größenordnung von mindestens 30°C. Es ist in jedem Fall notwendig zu vermeiden, daß der Aufbau der ersten Schicht nachteilhafterweise beeinflußt wird, wenn die Deckfolie erwärmt wird zum Anhaften an einer Oberfläche zum Abdecken.in the Generally, the softening temperature of the first and third Layer be significantly different, for example of the order of at least 30 ° C. In any case, it is necessary to avoid that the structure of the first layer disadvantageously affected is when the coversheet heats up becomes to adhere to a surface for covering.
